Two mechanisms of cooperative PSO (CPSO) were analyzed, and the load-balance requirement of equipotent CPSO mechanism was discussed. Then the CPSO load-balance architecture was set up, control parameters were chosen, and the criterion of PSO convergence degree was established. Finally, the control strategy for CPSO' load-balance was proposed. Two tests show that the proposed technique improved the...
The closed-loop control of stabilized platform in the modulated rotary steering drilling tool (MRST) is the key to the entire drilling system. Its core is the motor control system used in stabilized platform, which plays an important role in making the steady angle of stabilized platform adjustable and independent to the rotation of drilling string. Through the study of the stabilized platform, a...

The Wireless Sensor Networks (WSN) technology is employed in the open-pit mine slope detection system. When the open-pit mine slope is found abnormal, the WSN transmit data to the monitors timely in case of the unnecessary losses. Quantum genetic algorithm (QGA) is used in the multi-objective optimization problem of slope detection with WSN. It's for designing networking strategy of slope detection...

To solve time-delay of different-pressure casting's control system, Dalin algorithm and Smith prediction algorithm are separately used to design time-delay compensation controller of different-pressure casting computer control system. And with the two controller MATLAB simulation of different-pressure casting control object is carried on. The simulation results show that Dalin algorithm and Smith...
A new synchronization control scheme is proposed for Lorenz system. In order to obtain global stability, a state-depended dynamical error equation for the coupled systems is addressed. The control problem is converted into matrix inequalities by choosing proper control parameters. Additional optimization is given to reduce control parameters. Finally, the control problem is numerically solved by BMI...
The real-time monitoring of operational status in coal face can reduce the occurrence of risk effectively and prevent the further expansion of risk. This paper introduces a PC software in hydraulic supports control system based on VC++ through the investigation of coal face and the mathematical model of electric hydraulic and powered support control system. VC++ 6.0 was used to be the platform in...
RMU (Ring Main Unit) is small footprint, easy to use, but difficult to measure multiple analog signals, in response to these characteristics, this paper proposes a design of intelligent distribution ring main unit FTU (Feeder Terminal Unit) based on DSP. The system uses slot-type structure to carry on modular design, using CPLD for signal dispatching, it can measure up to 120 analog signals, digital...

It is provided of properties of data transmission and timing for each resource module with building the system DFG model with analyzing functions and algorithm. The basic method for optimizing resources...
The accuracy of flow measurement has become increasingly demanding with the rapid development of modern industry. Therefore, the high-precision measuring is very important for the flow liquid in the soft design and the hardware equipment. Since traditional flow-meter is difficult to filter out data errors, we propose a frequency-domain filtering of the data processing algorithm and design a complete...
The vibration test of the 4LZ-2 combine harvester is carried out on the location of the driver room. The main causes of the mechanical vibration and the maximum value of the vibration are determined. The anti-vibration test of the grain lost monitor is made. On above basis the anti-vibration performance of the monitor is studied and the monitor is redesigned. The reliability of the monitor is greatly...
The network worms have been a severe threat to the Internet with their occurring frequently, and also has brought about huge economic losses to the society. According to analysis the network worm characteristic, a Bayesian network worm detection method based on time model is put forward. This technology treats the failure rate of destination unreachable as the worm detection target. It determines...
In the paper, new results on H∞ control of impulsive systems with quantized feedback are presented. Applying the Lyapunov function theory, several sufficient conditions of the H∞ control problems are established for several classes of impulsive systems including linear uncertain impulsive system, linear impulsive system with nonlinear uncertainties, and impulsive system with decaying exponential,...
The paper used the ADALINE (adaptive linear neuron) structure rotate-speed recognizing method and applies the adaptive linear neuron to the non-velocity sensor combined with actual application conditions. The simulation results are get from MATLAB simulating first. Then the algorithm is applied to the biogas generator and gets the actual data.
Recently neural network is widely used in fault diagnosis. As the neural network method has the disadvantages of the slow convergence rate and the uncertain node number in neural network hidden layer, the results of fault diagnosis in complex devices are not satisfactory. This paper combines fuzzy logic and neural network, and presents a multilayer feed-forward fuzzy neural network with a serial structure...

Damages exist in every truss structure during long using process, so it's necessary to find the damages of using structures promptly avoiding collapse. Pole elements are the main members of steel truss structures, and the damage of these structures often appear pole elements, so the element damage information not node damage information must be adopted to judge the damage location. On the other hand,...
